AJGD- ⅡSwitch cabinet secondary debugging power cabinet

Overview

This switchgear secondary debugging power cabinet is used for various factory tests and handover tests after new or major repairs of high and low voltage switchgear, high and low voltage operating equipment, etc.

The hardware part of the testing system consists of 1 DC power output, 2 AC power output, and 3 three-phase current sources (used for protection testing). The DC power output and AC power output are controlled by a programmable power supply, while the three-phase current source is controlled by a separate power module for output
